1966 DKW F102 Tires

The 1966 DKW F102 uses two primary tire sizes: 590-13 and 600-13. Both are bias-ply fitments designed for 13-inch rims, and the covered Base sub-model can use either size depending on the wheel and tire setup on the car.

That means the first step is confirming what is mounted now rather than assuming every F102 uses the same replacement size. Check the current tire sidewall, measure the wheel if needed, and compare wheel width before ordering. Once the size is confirmed, the remaining decision is whether to keep a period-style bias-ply tire or consider one of the available radial equivalents.

The 1966 DKW F102 uses a 13-inch rim diameter with both of its primary tire sizes, 590-13 and 600-13. Even though the tire sizes differ slightly, they share the same basic rim diameter.

Rim diameter is only part of the fitment picture, so it is still important to confirm wheel width before selecting a tire. Available 590-13 products are built around a narrower rim-width range than the 600-13 options. On an older car, it also makes sense to verify that the wheels are original size and not later replacements that could affect how the tire sits and clears.

A 590-13 is a vintage numeric bias-ply tire size. The 590 refers to an approximate 5.90-inch nominal section width, written without a decimal, and the 13 identifies the rim diameter in inches.

This older sizing format does not read the same way as modern metric radial sizes, which is why it helps to translate the code before choosing a replacement. On a 1966 DKW F102, understanding that size designation helps separate the original-style bias-ply fitment from radial alternatives such as 165R13 or P165/75R13, which need to be checked against wheel width and vehicle clearance.

For the 1966 DKW F102, 590-13 is a primary bias-ply tire size. It uses a vintage numeric size format and represents the original-style construction choice for this application rather than a modern radial format.

Keeping a bias-ply tire usually matters most to owners who want the car to retain a traditional mid-1960s look and feel. A radial equivalent can still be considered, but it should be treated as a conversion decision rather than the same construction in a different label. Wheel width, clearance, and the condition of the steering and suspension become more important when changing away from the original-style setup.

Radial equivalents for 590-13 on a 1966 DKW F102 include 165R13 as an 80-series metric radial, P165/75R13 as a 75-series P-metric radial, and P175/70R13 as a 70-series P-metric radial. These are equivalent-size options, not the primary bias-ply fitment.

Each of those choices uses a different sizing convention, so the comparison is about profile family and fitment approach rather than simply picking any radial with a 13-inch rim. A 4- to 5-inch rim-width range is associated with the radial equivalents, and the final choice should be checked against the actual wheel width, tire clearance, and how the car is expected to be driven.

Start by confirming the tire size on the car, the 13-inch rim diameter, and the actual wheel width. For the 1966 DKW F102, radial equivalents are available for both 590-13 and 600-13, but the wheel still needs to suit the radial size being considered.

It also helps to inspect clearance at the fenders and steering components, especially if the car has had wheel, suspension, or ride-height changes over the years. A radial conversion can change the car's presentation and road feel, so many owners weigh that against restoration goals. Tire age and overall wheel condition should be reviewed at the same time rather than treating the tires as a standalone change.

The main considerations are staying with the correct 590-13 size, confirming that the wheel width matches the tire's rim-width requirement, and deciding whether the car should keep a period-style bias-ply setup. In this size, the available product centers on a BFGoodrich Silvertown Classic Bias Ply with a wide whitewall presentation.

That makes the decision more focused than on some larger collector vehicles, but it still matters. A narrower wheel setup may point naturally toward 590-13 rather than 600-13, and the sidewall appearance should suit the look you want from the car. If regular road use is a priority, compare the available radial equivalents separately rather than assuming they serve the same role as the bias-ply tire.

The available sidewall styles for 1966 DKW F102 tires include wide whitewall and narrow whitewall. In the current product mix, 590-13 appears with a wide whitewall, while 600-13 is offered with both wide whitewall and narrow whitewall variations.

Sidewall style is mostly an appearance decision once the correct tire size has been confirmed. A wider whitewall creates a more formal period-style presentation, while a narrower whitewall gives a subtler look. Since the 590-13 and 600-13 sizes do not share the same exact product mix, it helps to settle the fitment first and then choose the sidewall treatment that best matches the car's restoration direction.

BFGoodrich is the brand represented in the available tire options for the 1966 DKW F102. The products fall within the Silvertown Classic Bias Ply series and cover both 590-13 and 600-13 sizes with whitewall variations depending on the size.

Even with one brand in the mix, there is still a meaningful choice to make. The two sizes have different rim-width compatibility, and the 600-13 options include more than one sidewall presentation. That means the real comparison is not just brand name, but how the selected tire size, whitewall treatment, and intended use come together on the specific wheel setup your F102 is wearing.

A period-style 1966 DKW F102 starts with the correct primary bias-ply size already used on the car, either 590-13 or 600-13. Staying with a bias-ply tire preserves the vintage sizing format and keeps the visual character closer to what buyers expect on a mid-1960s European sedan.

After the size is confirmed, appearance comes down to details such as whitewall width and the overall stance the tire creates on the wheel. A radial equivalent may be useful for road use, but it changes the construction and often the visual impression. If exact originality matters, compare the chosen size and sidewall style against marque references or period photography for your specific car.

On a restored 1966 DKW F102, tire construction influences both look and character. A bias-ply tire keeps the car in its original-style sizing language and usually supports a more traditional sidewall presentation, especially when paired with a whitewall treatment.

A radial equivalent can change the visual balance even when it is chosen carefully within the same general fitment range. That does not make it wrong, but it does make the decision important for a restoration-oriented owner. For a car built in this era, the tire is a visible styling element, so construction choice should match the goal of the project rather than being treated as a purely mechanical replacement.

Yes, modifications can affect tire fitment on a 1966 DKW F102 even though the original tire sizes are relatively modest. Changes to wheels, suspension height, alignment settings, or body clearance can all influence whether a 590-13, 600-13, or radial equivalent works properly on the car.

That matters most on older vehicles that may have gone through decades of repairs or parts changes. A 13-inch wheel can still vary in width, and that directly affects which tire is appropriate. Any time the car has aftermarket wheels or a non-stock stance, it is wise to confirm wheel width and inspect steering and fender clearance before assuming the original fitment will behave the same way.

Before road use, inspect the wheels for damage or corrosion, confirm the tire size and rim match, and make sure the tires are inflated appropriately for their application. It is also smart to check for suspension looseness, brake drag, and any signs that the car may have uneven alignment or clearance issues.

A freshly mounted tire cannot compensate for worn steering parts, bent wheels, or a body clearance problem that was already present. On a collector-era car like the 1966 DKW F102, a careful walkaround after the first short drive is useful as well. Look for rubbing marks, unusual heat buildup, or pressure loss so any fitment issue is caught early.

590-13 tires on a collector 1966 DKW F102 should be maintained with regular pressure checks, visual inspection of the tread and sidewalls, and periodic review of overall condition even if the car is driven only occasionally. Low annual mileage does not stop tires from aging, and stored cars can still develop cracking or flat spotting.

Storage conditions matter almost as much as road use on a vehicle of this age. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the rubber, while occasional movement can reduce stress from sitting in one position. It also helps to recheck wheel balance, air retention, and any change in ride stance before a longer outing.
